In the given problem the best hint that is given for getting to the answer is that Evan's family drove at the same speed each day.
Then
On the first day the speed of the car = Distance/time
= 300/6
= 50 miles/hour
Then for calculating the distance traveled on the third day = speed * time
= 50 * 3
= 150 miles
Then on the third day they arrived at the park by driving 150 miles in 3 hours. So the correct option is option "C".
So we need to solve:
3ˣ⁻¹ = 9ˣ⁺²
To do this, we need to have the same base for both sides of the equation.
So let's go with the base of 3.
3² = 9
3ˣ⁻¹ = (3²)ˣ⁺²
3ˣ⁻¹ = 3²ˣ⁺⁴
Since the bases are the same now, we need to get rid of them and we would get:
x - 1 = 2x + 4
Subtract both sides by 2x:
-x - 1 = 4
Add 1 to both sides:
-x = 5
Divide both sides by -1:
x = -5
Answer:
y=1.61x
if my thinking is not wrong that is the answer.
